Bank 3 On-Chip Bus Control Register (0x00): OBCR
This register controls the on-chip bus speed for the KSZ8862M. It is used for power management when the external host
CPU is running at a slow frequency. The default of the on-chip bus speed is 125 MHz without EEPROM. When the
external host CPU is running at a higher clock rate, the on-chip bus should be adjusted for the best performance.

00: 125MHz.

10: 41.66MHz.
11: 25MHz.
Note: When external EEPROM is enabled, the bit 1 in Configparm word (0x6H) is used to
contol this speed as below:
Bit 1 = 0 , this value will be 00 for 125 MHz.
Bit 1 = 1 , this value will be 11 for 25 MHz.
(User still can write these two bits to change speed after EEPROM data loaded)
